ALFRED REDFERN, OF PHILADELPHIA, PENNSYLVANIA.

PORTABLE WATER-H EATER.

P CIF N forming part of Letters Patent No. 670,812, dated March 26, 1901.

Application filed June 11, 1900. Serial No. 19,948. (No model.)

To (all whom, it may concern:

Be it known that I, ALFRED REDFERN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Portable Water-Heaters, of which the following'is a specification.

This invention relates to new and useful improvements in portable water-heaters; and its primary object is to provide a simple and durable device which is small and light and which is capable of quickly heating, water which circulates therethrough.

To these ends the invention consists in providing a casing within which are mounted a suitable number of depending tubes, each of which is partitioned into two compartments which communicate at their lower ends, said tubes communicating with each other at the tops thereof.

The invention also consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which--- Figure l is a perspective view of a heater embodying my improvement. Fig. 2 is a plan view of the tubes and their connections used therein. Fig. is a section therethrough. Fig. 4 is an elevation, partly in section, of a modified form of heater. Fig. 5 is a similar view of a further modification, showing same in position upon a stove. Fig. 6 is a transverse section through either of said heaters. Fig. 7 is a section through a modified form.

Referring to said figures by numerals of reference, 1 is a casing of any desired form and material and having a gas-inlet 2, which communicates with a burner 3 (shown in Fig. l) of any desired form. The casing, when of the form shown in Fig. 1, is preferably provided with a series of depending tubes arranged in the manner shown in Fig. 2. These tubes are arranged in parallel series, said series being connected in the manner hereinafter more fully described. Each series is preferably formed of two or more-tubes 4, each of which is closed at the bottom and provided with an internally-threaded opening at the top, adapted to receive a cap 5. Depending from this cap is a partition 6, which fits snugly against the opposite sides of the tube 4, but which is shorter than the tube, and therefore forms an opening for the passage of Water thereunder when the same is in position within the tube. The tubes 4 of each series are preferably cast in one piece and are provided with connecting-pipes 7 within the upperends thereof at points below the caps 5, whereby water may pass from one tube to the other, as is obvious. One of the end tubes of one series is provided near its upper end with a water-inlet pipe 8, while the tube at the opposite end of said series has an elbow 9 extending therefrom, which is threaded at its end and adapted to be engaged by a nut 10, which is internally threaded and is also socured to the elbow of the adjacent series of the tubes. It is obvious that by this construction water entering the pipe 8 will flow down one side of each tube, under its partition, and up within the opposite side into the adjacent tube, said water passing from tube to tube of each series and finally out through the outlet 11, which corresponds to the inlet 8, heretofore referred to.

Where the casing is cylindrical, as shown in Figs. 4 and 5, the tubes instead of being arranged in parallel series are preferably placed in the position shown in Fig. 6.

While I have described the tubes as being provided with threaded caps upon which are formed the partitions, I do not limit myself to this construction, for, if desired, each series of tubes may be covered by a single plate 12, as shown in Fig. 7, and this plate may have partitions 13 depending therefrom at proper intervals. Where a plate of this character is employed, the same is secured to ears 14, formed upon the end tubes of each section. If desired, however, in lieu of the plate and screw-caps, a casing 15 may be fitted over each series of tubes. This casing, as shown in Fig. 8, is divided into compartments 16.by depending partitions 17, which are adapted to extend downward into the tubes. Openings are formed within the bottom of the easing adjacent to each partition, and these openings register with the openings within the top of the tubes to which the casing is secured. I00 When a device of this character is employed, the water inlets and outlets are preferably secured to the casing, and it is not necessary to employ the connecting-pipes 7, heretofore referred to.

In Fig. 9 I have shown the tubes provided with a partition 18, which is oval in section, as shown, thereby forming an air-space between the currents of water within the tube.

It is obvious that various other modified forms of tubes may be employed, if desired, and I do not therefore desire to restrict myself unnecessarily to the forms shown and described. I

It will be seen that while the device is especially adapted to be heated by gas the same may be employed upon an ordinary range, as shown in Fig. 5, and in such case the casing 19 shown in said figure is open at the bottom, so as to permit the heat to pass unobstructed from the stove to the tubes.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. In a water-heater, the combination with a casing; of a series of depending communicating tubes therein, each having a rounded bottom formed integral therewith, said series formed in one piece; a threaded inlet to each tube at the top thereof; a cap detachably secured within the inlet of each tube; and a partition extending from said cap into its tube and adapted to retard the flow of water therethro ugh.

2. In a Water-heater, the combination with a casing; of two or more series of depending communicating tubes, each series formed in one piece and each tube having a rounded bottom formed integral therewith; a water inlet and outlet; an elbow to each series; means for detachably connecting the adjacent elbows of each series and permitting the passage of water therebetween; a threaded inlet to each tube; a removable cap within each inlet; a hollow partition extending from each cap into. its tube and adapted to retard the flow of water therethrough.

3. In a water-heater, the combination with a casing having a burner therein; of a series of tubes each havinga rounded bottom formed integral therewith; means connecting the adjacent tubes at the sides thereof and permitting the passage of water through one tube to the other successively; a threaded inlet to each tube; a removable cap therein; a partition extending from each cap into its tube to a point adjacent to the bottom thereof.

4. The combination with a casing having apertures therein and a top; of a series of depending comm unicating tubes secured within the casing, each having a rounded bottom formed integral therewith, said series being formed in one piece, a threaded inlet to each tube at the top thereof, a cap detachably secured within the inlet of each tube, and a partition extending from said cap into its tn be and adapted to retard the flow of water therethrough.

In testimony whereof I affix my signature in presence of two witnesses.
